CLOSET-BOWL.

Specification of Letters Patent.

Patented May 9, 1216.

Application filed May 7, 1915. Serial No. 26,590.

To all whom it may concern Be it known that 1, ANDREW F. BARRON, a citizen of the the United States, residing at lVatervliet, in the county of Albany and State of New York, have invented certain new and useful Improvements in Closet- Bowls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to closet bowls, and the primary object of the invention is to provide a closet bowl which is constructed so as to carry away the obnoxious odor which arises after the use of bowl, and also to provide means for efliciently flushing the bowl for preventing the accumulation of paper or the like therein, and to increase the sanitary proclivities of the bowl.

Another object of this invention is to provide auxiliary air passages, which lead from the shoulder of the bowl rearwardly, to the rear edge of the same, for carrying off the odor from the bowl.

lVith the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of the improved closet bowl, Fig. 2 is av vertical section through the bowl, and Fig. 3 is a detail sectional view of a part of the construction of the bowl.

Referring more particularly to the draw ings, 1 designates the commode or closet bowl, which has a base 2 secured to the lower edge thereof, for attaching the bowl to the floor of a room, and which has an upper seat portion 3, formed upon the upper end of the bowl body 1. The bowl 1 has the ordinary flush tube 4 mounted about the seat section 3, which tube is provided with a plurality of circumferentially spaced openings 5, for permitting of the flow of water into all parts of the bowl for the purpose of flushing the same. The tube 4 has communication with the water inlet opening 6 of the bowl in the ordinary manner, and it has a relatively short tube or tube 12 has its upper end slightly flared,

and it is curved to conform to the curvature of the rear wall of the inner recess formed Within the bowl. The tube 12 terminates a short distance below the lower edge of the apron 11 and it rests against the rear wall 1% of the bowl, so that the water flowing therethrough will efficiently flush the rear wall of the bowl.

A tube 15 extends downwardly through the rear section of the bowl 1, and it has communication with the passageway 6. The tube 15 extends downwardly, and has its lower end curved, so that its lower end will rest upon the bottom of the recess of the bowl a short distance outwardly from the mouth of the trap 10, thereby facilitating the ehicient flushing of the bowl, by forcing a stream of water outwardly at the mouth of the trap for aiding in forcing the contents of the bowl into the trap and outwardly through the same, through the outlet pipe 16 which may be connected with any suitable type of sewerage construction.

The rear side of the bowl 1 has a projection 20 formed thereon, which is provided with an open space 21 formed therein. A pipe 22 communicates with the open space 21, and it may be constructed in any suitable manner, such as the ordinary type of nipple used for forming air or fluid-tight connections between the closet bowl and the pipes leading thereto or therefrom. The pipe 22, which communicates with the space 21, is adapted for communication with any suitable type of vent pipe or passageway leading out of the building in which the bowl is mounted, and its purpose is for carrying away the obnoxious odor arising after the use of the bowl.

The bowl 1 has projections 23 formed upon its opposite sides, which communicate with the interior of the bowl beneath the apron or tube 4 thereof, as is shown at 24:. The passageways 23 extend around the outside of the bowl 1 and have communication with the space 21, as is shown at 25, so that the odor from the bowl will pass around through the passageways and into the space 21 and out of the same through the vent openings. The vent opening or pipe having atmospherical communication, will create a draft or air suction through the space 21 and the passageways 23, maintaining a fresh and comparatively pure state of air within the closet bowl, thereby increasing the sanitary proclivities of the same, and preventing the passage of foul or obnoxious odor from the bowl into the room in which the same is positioned.

In Fig. 3 of the drawings, one of the nipples, such as are employed for connecting the water flushing pipe and the air vent pipe 22 to the bowl is shown. This construction includes a nipple 30, which has its lower or inner end 31 flared, for seating in the flared portions of the openings. The shank 31 of the nipple, which projects out of the bowl, is externally screwthreaded, and a union 33 is mounted thereon and held in place by a lock nut 34, for forming a substantially fluid-tight connection between the pipe and the openings in the bowl.

In reducing the invention to practice, certain minor features of construction, combination, and arrangement of parts may necessitate alteration, to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

wardly from the mouth of said trap struc-' ture, the upper end of said tube communicating with said water inlet opening, the lower end of said tube being positioned for ejecting a stream of water over the bottom of the recess of the bowl, a second tube extending downwardly through said apron and being curved to conform to the curvature of the upper portion of the rear wall of the recess formed within the bowl, said relatively short tube having its upper end flared and communicating with the water inlet opening for conveying a stream of water for discharge along the rear wall of the recess of the bowl, said bowl beingprovided with an air space formed therein rearwardly of said tubes, said bowl having openings formed in the side thereof forwardly of said air space, and extensions formed upon the outer surface of said bowl and connect ing said vent opening with said air space.

In testimony whereof I affix my signature in presence of two witnesses. 7
